How to Choose a Concrete Contractor in Queens

A bad concrete contractor will cost you more than the bad concrete. A driveway poured wrong is a tear-out and re-pour 5 years from now. A sidewalk poured wrong is a NYC DOT violation. A foundation poured wrong is structural damage. The good news: it's not hard to filter out the bad contractors before you sign anything. Here's the actual process.

Step 1: Verify the License

In NYC, home improvement contractors over $200 of work must have a Department of Consumer and Worker Protection (DCWP) Home Improvement Contractor (HIC) license. For sidewalk and DOT right-of-way work, the contractor needs a separate NYC DOT permit registration.

Ask for the HIC number. Then verify it on the DCWP website. It takes 2 minutes. Skip this and you have no recourse if anything goes wrong.

Step 2: Get Proof of Insurance

You want two things in writing:

• General liability insurance (typically $1M minimum). This covers damage to your property if something goes wrong on the job.
• Workers' compensation insurance. If a worker gets hurt on your property and the contractor doesn't carry workers' comp, you can be on the hook personally. This is non-negotiable.

Ask the contractor to have their insurance company email you the certificate of insurance directly. A printout they hand you is easier to fake than one that comes from the carrier.

Step 3: Get at Least Three Bids

Bids tell you a lot more about a contractor than their website does. Three bids on the same scope of work in Queens will usually fall in a range — say, $7,000 to $10,000 for a 600 sq ft driveway. The cheapest is almost always cutting something. The most expensive may be padding. The middle is usually closest to fair.

If a bid is dramatically lower than the others, that's not a deal — it's a warning. Ask what's different about their scope. Usually it's base depth, rebar vs mesh, or PSI mix.

Step 4: Ask the Right Questions

A contractor who knows their craft has confident, specific answers to these. A contractor who's winging it gets vague.

• "What PSI mix are you using?" 4,000 PSI is standard for residential driveways and patios. 3,500 is the bare minimum. Anything below 3,500 is wrong for this kind of work.
• "What reinforcement?" #4 rebar on chairs in a grid pattern is the right answer for driveways. Wire mesh is acceptable for sidewalks but lazy for driveways.
• "How deep is the gravel base, and what's it compacted to?" 4–6 inches of compacted gravel is standard. Compacted with a plate compactor in lifts, not just dumped.
• "How are you placing control joints?" Saw-cut joints, no more than 10 feet apart, cut within 24 hours of the pour. Hand-tooled joints are second-best.
• "How long before I can drive on it?" 7 days for cars, 28 days for full strength. If they say "tomorrow," they don't know what they're doing.
• "What's your warranty?" Should be in writing. Should cover workmanship for at least 2 years. Should clearly state what's covered and what's not.

Step 5: Check Their Recent Work

Photos on a website are easy to fake or buy. Two better moves:

• Ask for 2–3 addresses of recent jobs in Queens. Drive by them. Look at the joint placement, the surface finish, the edges.
• Read Google reviews — but read the negative ones especially. One bad review is normal. A pattern of complaints about the same issue (no-shows, change orders, leaks) is a sign.

Red Flags to Walk Away From

• Cash-only or "off the books" pricing. Often means no insurance, no license, no recourse.
• Door-to-door pitches with "leftover concrete from a job down the street." Classic Queens scam. The concrete is bad, the contractor will be gone tomorrow.
• Demanding more than 30% deposit. Standard is 10–25% to lock in materials and schedule. More than that means cash flow problems.
• No written contract. Walk away. Period.
• Vague scope. A real contract specifies square footage, concrete PSI, base depth, reinforcement type, joint placement, finish, sealer, and timeline.
• Pressure to decide now. "This price is only good today" is a tactic, not a real constraint.
• No physical address or local presence. If you can't find them on Google Maps with a real Queens address, be careful.

What a Good Contract Should Have

• Itemized scope of work — what they're doing and what they're not
• Specific materials (PSI, rebar size, base depth, sealer type)
• Total price, deposit amount, and payment schedule
• Start date and estimated completion date
• Permit responsibility (who pulls, who pays)
• Workmanship warranty terms in writing
• Cleanup and disposal responsibilities
• License and insurance information on the contract itself
